# Time Series Completeness — Record Quality Audit + Equal-Width Histogram

> Time Series Completeness — Record Quality Audit + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Runs two local analytical reports (record quality audit and equal-width histogram) on up to 200 time series completeness rows containing observed and expected data point counts.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability time-series-completeness-record-quality-audit-equal-width-histogram-caa8ecdc -d '<json body>'
```

Example prompt: Can you run a record quality audit and a 10-bin equal-width histogram on my time series completeness data for the observed_points field? I have 5 rows: row-1 for dataset-alpha on 2024-01-01 with 95 observed and 100 expected, row-2 on 2024-01-02 with 80 observed and 100 expected, row-3 on 2024-01-03 with 100 observed and 100 expected, row-4 on 2024-01-04 with 60 observed and 100 expected, and row-5 on 2024-01-05 with 45 observed and 100 expected.

## When to prefer this

Choose this endpoint when you have pre-collected time series completeness data (observed vs expected point counts per date and group) and need two fast, local statistical reports — a quality audit and a histogram — without needing live data lookup, external predictions, or professional assessment. It is cost-effective at $0.01 USDC for both reports on up to 200 rows. Prefer it over general analytics platforms when you want a lightweight, deterministic, reproducible analysis of completeness records in a single API call.

## Known failure modes

- More than 200 rows submitted — request rejected with validation error
- bins value outside 1–30 range — schema validation failure
- Missing required fields (row_id, date, observed_points, expected_points) in any row — row rejected or error
- date field not in YYYY-MM-DD format — pattern validation failure
- All values null for selected field — histogram may return empty or degenerate result
- Payment failure — x402 payment not processed, request not fulfilled

## How this service works

Time series completeness — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied time series completeness records (observed_points, expected_points). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two independent analytical reports: (1) a record quality audit flagging completeness issues, nulls, and anomalies across the supplied rows of observed_points and expected_points; and (2) an equal-width histogram distributing the selected field (observed_points or expected_points) across the requested number of bins. Both reports are computed locally using shared analytical engines with no external lookups.
